So lets say I had $10,000 in health expenses last year, and I decided to itemize them. For simplicity sake lets say that I was able to deduct $5000 of them as that was the amount over 7.5% of my AGI.

Am I still allowed to use HSA funds to reimburse myself in the future for $5000 of the expenses that weren't deducted? or because I itemized at all, all of it is marked as non reimbursable?
